Low-emission zones and restricted access in Europe: what motorhome travellers should check

Many European cities now restrict access for older or more polluting vehicles, and the rules do not stop at the border. A motorhome that is fine on the campsite ring road can be a problem two kilometres further on, in a historic centre or low-emission zone. Fines usually arrive by post weeks after the trip, sometimes from another country. This article explains the principles behind the zones and how to check a route without relying on a table that would be out of date by next season.

How the zones work

Low-emission zones, called ZFE in France and Umweltzonen in Germany, admit vehicles by emission class. The class is shown by a sticker, such as the green badge in Germany or the Crit’Air sticker in France, or cameras check the number plate against a database. Italy’s ZTL (zona a traffico limitato) is a restricted-traffic area, usually around a historic centre, that promobil describes as reserved for residents and some other vehicles. London, according to Transport for London, uses daily charges for vehicles that do not meet the standard. All of this is decided locally, so no single list can be trusted for long.

Why motorhomes are often affected

Three things decide whether a zone applies to you: the vehicle category, the emission class and the weight. In France, promobil reports that motorhomes under 3.5 tonnes are treated as passenger cars. In London, motor homes over 2.5 tonnes gross vehicle weight fall under the Low Emission Zone even for private use, and Transport for London says a converted vehicle counts as a motor caravan only if the DVLA classifies it that way. Many campers are diesels, and the Euro class is what most zones test. In historic centres, size alone can keep large vehicles out, as promobil notes for Italy. Before you travel, read three entries in your registration document: vehicle category, emission standard and permitted gross weight.

Country by country: principles instead of tables

Germany: promobil counts 37 environmental zones as of August 2024, and entering them requires a green sticker. The Austrian club ÖAMTC gives a fine of 100 euros for entering without one and describes no blanket exemption for foreign vehicles; it also reports diesel driving bans in Stuttgart, Munich and Darmstadt. The ÖAMTC issues the sticker for cars and motorhomes up to 3.5 tonnes, heavier vehicles get it from inspection organisations such as DEKRA or TÜV. France: anyone entering a ZFE needs a Crit’Air sticker, including vehicles registered abroad. According to france.fr it must be ordered on the official government site, costs 4.91 euros for foreign vehicles and takes five to ten days to arrive; the fine is 68 euros for a passenger car. The National Assembly voted in May 2025 to abolish the zones, but on 21 May 2026 the Conseil constitutionnel struck the provision out of the simplification law as a legislative rider (LCP, Banque des Territoires). The zones are therefore not abolished by that law; check before you go which rules apply in each city. Italy: a ZTL is signed at its edge, and “varco attivo” means, according to promobil, that camera enforcement is active. Fines are roughly 80 to 335 euros per passage, each entry counts separately, and notices often arrive weeks later.

United Kingdom: London’s Low Emission Zone covers motorhomes over 2.5 tonnes and requires the Euro 3 particulate standard. According to Transport for London the ULEZ applies across all London boroughs, with a daily charge of £12.50 if the vehicle does not comply. TfL offers a number-plate checker. How foreign-registered vehicles must register or pay: check before you go. Netherlands: milieuzones.nl states that the rules apply to foreign vehicles too and that advance registration is mostly not needed. The rules mainly concern trucks and coaches and sometimes diesel cars and vans, so the municipality’s page is decisive. Belgium: in Flanders, authorised foreign vehicles must register once, free of charge; registration in Ghent also covers Antwerp, while Brussels needs its own, and day passes are valid only in the city where they were bought. Switzerland: Geneva applies Stick’AIR only during forecast or confirmed pollution peaks, between 6:00 and 22:00, to Swiss and foreign vehicles alike, and recognises Crit’Air stickers. Austria: we have no verified overview for motorhomes; check before you go with the state or city concerned.

Checking your obligations and registering

Work from the route to the rules. List the cities you will pass or stay near, then open the official page for each: the French government platform Itineriz for ZFE routes, the Transport for London checker, the Flemish city tools that take number plate and date of first registration, or the Urban Access Regulations site that milieuzones.nl recommends. Registrations and stickers are usually done online and can take days or weeks, so start before departure. Treat the fines quoted (100 euros in Germany, 68 euros in France, 80 to 335 euros per Italian ZTL passage) as an indication of risk; they can change. Some temporary zones are announced only 24 hours ahead, according to promobil. For legal questions, ask the city, the competent authority or your automobile club; this article is not legal advice.

Park outside, ride in

The most reliable strategy is to avoid the zone altogether. Promobil recommends parking outside the ZTL and exploring by public transport, bike or on foot. Look for a campsite, a Stellplatz or a park-and-ride car park at the edge of town with a tram or bus link, and check beforehand that it lies outside the zone. Plan the route on official zone maps and do not rely on the satnav alone, because promobil says navigation devices do not reliably mark ZTLs. Note a parking spot outside the zone in advance, especially on day trips with a car towing a caravan, and avoid driving in and out while searching, since each entry can be fined separately.
